Optional when transporting hazardous materials. In general, a tank endorsement is required to a drive tank vehicle used to transport liquids or gases. This applies to both hazardous and non-hazardous materials.

6 . Poisonous fumes can enter the cab due to:

Under-inflated tires. Defects in an exhaust system are very dangerous because they can cause poisonous fumes to enter the cab or sleeper berth.
